This Gastly was used by the Jenny on Mandarin Island North. It was able to use its ghost moves to find Butch, Cassidy and their Drowzee, who had brainwashed all of the other Pokémon on the island, being immune to the brainwash itself. It has an unusually high Special Defense, as it was later used to protect Ash from the combined attacks of the controlled Pokémon. Gastly is kept outside its Poké Ball.
